In the last year or so my tailbone has become very sore after 30+ minute street rides. Ditto if I ride to work several days in a row (10min rides each way). I had a new seat put on a few years ago and it's medium density (Guts Racing foam & cover). It helps a little to sit so my tailbone isn't directly on the seat, but that gets uncomfortable after a while. I'm on a KTM 640 LC4. I've never had problems with tailbone bruising before, and didn't have any accidents on or off the bike that could have affected my tailbone. So I have a couple questions.. 1) Anyone else have this problem? 2) Will soft foam break down quicker than medium density foam?
